I claim as my invention: l

1,'The combination of an axle, a frame yieldingly mounted on the axle, a driving element rigidly secured to the frame, and

` a driven element on the axle, With a bearnecting the crank of the crank shaft, withA said other cranks. y

3. The combination with an axle, ot a bearing mounted on the axle, a frame, springsrbctneen the bearing and the frame, a driving shaft mounted in bearings on the frame, a crank on the axle,`a crank on the driving shaft, a crank shaft', a bearing lhere- '1 for, springs allowingl the bearing to yield under pressure, and rods connecting the crank of the crank shaft to said other cranks.

Il. rlhe combination of two4 axles, Wheels thereon, bearings for the axles, a spring supported frame carried by the bearings, crank pins on the wheels2 a rod connecting the two crank pms, a driving shaft mounted on the frame, a bearing on the frame, springs mounted o n each side of the bearing to allow it to yield longitudinally, a crank shaft mounted in the bearing, a crank on the driving shaft, and a rod connecting the crank of the driving shaft with the'erank shaft, said crank shaft being connected in turn to the crank upon one of the wheels of the axles.

5. The combination in an electric locorno tive, of two axles, Wheels having crank pin's thereon, a rod connecting the two crank pins, boxes on the axles, a frame spring supported on the boxes, an electric motor carried by the frame, a driving shaft geared to the motor and rigidly mounted on the frame, a bearing mounted in the frame and having springs resting against each end thereof, said bearing being free to move longitudinally under pressure, with a crank shaft mounted in the bearing, a rod connecting the crank shaft with the driving shaft, and a rod connecting the crank sh'aft With the crank pin on one of the Wheels of the locomotive.

(5. rl`he combination in a yielding bearing, of a frame having pedestals, a bearing box mounted between the pedestals and held in place vertically, plates mounted between the pcdestals and the bearing, spring plates having members extending on each side of thev pedcstais and resting against the first men. tioned plates, with springs back of Said spring plates so as to allow the bearing to `yield when subjected to undue pressure.

In testimony whereof` I have signedmy' name to this specilication, in the presence of two subscribing witnesses.
